WINDOW-enana OPERATOR.

Application led May 8,

To all 'whom t may concern:

Be it known that I, THOMAS BArA, a citizen of the United States of America, residing at Smock, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Window-Shade Operators, of which the following is a specification;

"This invention relates to new and useful improvements in window shade operators.

An important object of the invention is to provide means for raising and lowering a window shade with the controlling portion of the apparatus conveniently positioned to the Operator.` Y

A further object of the invention is to provide an apparatus of the type described that may be easily and quickly applied to the Ordinary Window frame Without neoessitating any changes being made to the same.

A further object of the invention is to provide a shade operator of the above mentioned type which is strong and durable, and one that may be placed upon the market at a reasonable price. v

Other Obj ects and advantages of the invention will be apparent during the "course of the following description;

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a front elevational view of a window frame with a window shade and operating means properly positioned there- O11 Figure 2 is a fragmentary elevational view of the upper right hand corner of the window frame and shows a portion of the opel ating mechanism for the said shade.

ed for supporting the perpendicular drive shaft associated with the mechanism em bodied in this invention.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention7 thenumeral 5 designates in general a window frame having the usual window sashes 6 slidably mounted in the side vertical portions 7 and 8 which are connected at their upper ends by the top frame portion 9.

Secured to the top frame portion 9, as by the screws l0, is a horizontal supporting plate 1l having at its extreme right end an angularly arranged foot portion 12 which is provided with lugs 13 adapted for engaging in mortise portions 14 formed in the extreme upper ends of the perpendicular supporting plate 15 secured to the vertical window frame portion 7 as by similar screws 10.v

Suitably secured to the horizontal `supporting plate 11 are shade brackets 16 Aadapted for receiving pins or the like carried by the extreme outer ends of the shade roller 17 which has suitably secured thereto the shade 18. Positioned adjacent the eX- tremeV right handend of the shade roller 17 is a bevel gear 19 which is rigidly connected i' vided with a rigidly connected bevel pinion 23 which is constantly in mesh with a bevel gear 24 rotatably retained upon the horizontal axle pin 25 and having secured thereto a handle member 26 which is adapted for actuating the said gea-r 24. Referring particularly to Figs. 1 to 3 inclusive there is shown la pinion 27 rigidly secured to the upper end of the perpendicular shaft 22 and constantly engaging a gear 28 which is rigidly connected to a spur shaft 29 suitably journaled on a substantially U-shaped bearing bracket 30, the upper end of the said spur shaft 29 being provided with a beveled pinion 31 that is constantly in mesh with the beveled gear 19 rigidly secured to the shade roller 17.

The operation of the bevel gear 24 by a person grasping the handle 25 will actuate the perpendicular shaft 22 in either direction, in accordance with the direction of operation of the bevel gear 2li, lfor raising or lowering the window shade 18 due to the connection between the pinion 27 formed rigidly with the upper end of the perpendicular shaft 22 with the gear 28 that is rigidly mounted upon the stub shaft 29 having a bevel pinion 31 constantly meshing with the bevel gear 19 formed rigidly upon the shade roller 17. It is very apparent that the entire shade operating mechanism may be removed from the window frame 5 by simply taking out the screws 10 provided for retaining the supporting plates 11 and 15 upon the top frame portion 9 and vertical side portion 7. It is to be understood that the form of this invention herewith shown and described is to be taken as the preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
